We have many HapAC's and SXTsq's that are out of space.

They cannot update certificates(many are too old to use ram for crl-store), they cannot upgrade their OS.
Some are so bad they can't even run scripts to enable vpn access etc.

The only extra package we use is tr069

We have tried the space fix npk without luck,

Fortunately most of the old FW hap's are paired with SXT HG5 AC's which appear to predate the move to 16mb (Seriously??)

Still this is a pretty dire situation.
